Justin Davis ran for 74 yards and a touchdown and No. 24 USC’s defense picked up for its shaky offense, masking mixed performances by battling quarterbacks Cody Kessler and Max Wittek in a 30-13 win over Hawaii on Thursday night.

Kessler, who threw two interceptions in the no-tackling scrimmage, but also made the game’s best throw on a 55-yard TD pass to Nelson Agholor, is the leading candidate to win the QB spot after Matt Barkley.
